How to use AddOptionalPackageAsync?

Tanaka_Jimha Alright, I've got the github repo up now, it is here:

https://github.com/davidanthoff/winjulia

You won't be able to run the build steps because you also need various builds of Julia itself, and setting that up is complicated, but it should give you an idea of what scripts I'm using to build things.

I'm also hosting the packages that I've created online now at https://winjulia.s3-us-west-1.amazonaws.com/index.html, so you and the dev team should be able to run the installer etc. on your own system and collect logs.

Here are some random comments that maybe are helpful:

• The link "Install Julia" on that S3 website that I posted links to the appinstaller file. It will install the "Julia" package, and one of the optional packages, namely Julia-1.4.1. There are two other optional packages (Julia-1.4.0 and Julia-1.4.2), and the website has links to all three optional packages.
• Installing any of the three optional packages via the weblink from that S3 site works.
• What I want to do is install optional packages from in-app code, though. The specific code that I'm using for that is https://github.com/davidanthoff/winjulia/blob/4ac34b6d0f4a434ef1902ecf24c17a8a3da65e64/launcher/main.cpp#L97, and that is also the part of the code that errors. If you install the main "Julia" app from the website that I linked to and run it, you will see an error message, and the code that I linked to in this item here is where that error occurs.

Let me know if this helps or if you need any more information!
